If large caves exist on Mars, it would be a step in the right direction. What about oxygen, is there any known source on Mars? How much water exists on Mars? Humans will have to bring everything necessary to sustain Life until we could start thatever manufacturing necessary.
Could people get used to living underground? Or somehow creating a better way to work in and under the surface of another planet? We can hardly dig through the Earth effectively.
Already done a picture of a Google server farm was spread around already.
I'll believe it when I see it. Gonna be small teams of researchers for 100+ years unless robotic construction improves. Don't see that on Earth. Tech is invented and then disappears into the ether.
A colony on mars will definitely find lots of archeology, it's been seen too many times for it not to exist. At a stretch I'd say they might find valuable artifacts from ancient civilisations. If a mars colony came into contact with one or more alien civilisations trade relations and passing of knowledge could see those colonies becoming independent.
We've spent billions of years evolving in the Earth's gravitational field and need to know a lot more about how reduced gravity will affect sarcopenia in adults and fetal development in pregnancy before we invest in colonies on Mars. Rotating donut shaped colonies have been studied. They can be built on the moon with the "floor" angled so centrifugal acceleration plus the moons natural gravity add up to Earth normal. The engineering and logistical challenges of this type of colony are a lot less than a Martian colony and it could probably pay for itself by shipping helium 3 back to Earth for fusion reactors.
Caves for sure! Surface domes are too vulnerable. In KSR Mars trilogy, humans start by putting containers in the ground as make-shift habitats. Later habitats are build below the surface. Above surface can be done later. Would be nice to have a magnetosphere around Mars though.
A combination of both would be needed. The caves for most things and domes for food production. Domes do not have to be big and could have covers that could go over them for major events to protect them. The main problem is going to be the dust. The caves could house tubes that would be like structures that were built in Greenland during the Cold War. They could have airlocks for going outside into the caves so the caves themselves would not need to be air tight. Insulating the structures inside the caves would be easier than insulating the whole cave.
The lord told me to lay down in green pastures. I don’t see any green pastures on the moon or mars, so I think I’ll stay here. You go😆
It makes sense, using existing lava tubes that you only have to seal from the hostile surface any point it is exposed. Obviously you would want to line the walls to strengthen them and prevent future breaches. Much more practical than a domed city.
As for getting views of the surface they have this neat new invention called closed circuit video. Much less risky than a window or a dome.
As for food it could start with sprouts for vitamins and adding protein, fiber and starch to fill them up.
By sending up fish fry like say talapia could be a great start to farming protein assuming you can find a source of water. Imagine a pond running down the length of the
tunnel middle not only provides you with a lovely view, but also holds fish to eat. Like one long huge aquarium. As you expand you can add other fry like catfish, trout, grouper, clams, muscles etc … and all of them pooping out fertilizer for the plants that keep their water clean, and yes even feed them too.
The water can be filtered through aquafarms that would grow vegetables to expand their diets. And the roots stems and leaves not eaten could be used to make a mulch that could amend the dirt to grow larger or other plants.
You could send chicken chicks up too, to create a supply of eggs and meat. Ducklings and goslings are another expansion to the protein source.
With human and animal sewage there is a steady source of fertilizer that could be added to processed soils to expand to other plants that filter the air and provide them greenery to live around.
Power could come from a network of surface or near surface micro reactors and thermal electric generators that not only power to run the colony but also heat to warm it. And if you ran them at say 70% capacity then if one ever did go down or need maintenance then the others could take up the slack until it is repaired or replaced. Also several smaller reactors is much less vulnerable to a single disaster than is one large reactor.
Come to think of it we could even start doing alot of these things here on earth too, just to practice and get the process down. Of course we would have to put up with decreasing our reliance on fossil fuels a time bit, and possibly making food more plentiful and cheaper to buy a tiny bit. Maybe even lowering the polution levels a smig. But I'm sure we could suffer through that burden. Don't you?
I think mass-producing stainless steel sheet metal will be practical, on Mars. Also, mass-producing PVC could also be practical, given enough energy. You could build stainless steel buildings using cold-welding (pushing steel together in the absence of oxygen, causes a bonding like pushing clay together). Pure PVC is highly insulative, fire-resistant, and transparent with a slight blue tint. Anyway, I'd build villages skinned with sheet metal, and structured with corrugated or bent sheet metal. I'd build the roof to overhang a big, cover the top with up to a meter of regolith, use blown glass bricks for windows, and coat the interior with a PVC membrane. This would be buildable with all materials and energy from Mars and be very safe. It would protect from small meteors, retain warmth, allow sunlight in, and hold air in really well.
So smelting iron and nickel (very abundant on the surface) can be done with a lightweight titanium crucible and a solar concentrator (for heat). Purification during smelting (normally done with things like borax) can be done by injection of pure oxygen. Pickling and cold rolling to make highly impact-resistant and malleable stainless steel also shouldn't require too much equipment. PVC can be made using the abundant salts in the ground (for chlorine), CO2 in the air, and steam — using the pressurized steam method. 1 meter of regolith is enough to block the cosmic rays to more than safe levels and also will catch small meteors that are most typical. Larger impacts blowing debris laterally should also not be too damaging, as cold rolled steel is hightly impact-resistant.
A PVC member is very insulative and abrasion resistant, however, if the habitat is separated a bit from the ground, heat dissipation should be very slow. This is because the atmosphere is so thin. Although very cold, transference of heat outward should be substantially slowed due to the distance between molecules in the atmosphere.
That said, I do also like the idea of lava tubes. I drew up designs for an inflatable wall with airlock to seal off two ends of the tube. Smoother lava tubes tend to be sealed somewhat air tight due to the melted nature of the walls. However, this would not be sufficient because one leak is too many. I'd spray it down with a hot PVC membrane. The problem is that Martian lava tubes are far larger, on average, than Earth ones. I visited a lava tube in Cheju-do island, Korea. It was about 10 meters wide. The lava tubes on Mars are vastly larger due to the lower gravity and double the metals content in the basalt. So that's great if you can seal it but much harder to seal.
Another idea is to melt out a city in one of Mars' large tropical glaciers. You'd need to build a surface airlock but it would be vastly faster and easier to melt out large spaces in which to live. Inside an ice cave, you can create comfortable room temperatures because the vast ice behind the walls helps prevent melting. Also for higher temperatures, such as for growing tomatoes, you could use an insulative membrane in the grow rooms. Obviously, you will be using LED grow lights. You can make tables, chairs, beds, sofas, from ice and just need to cover them with an insulated fabric…. You could even make plates and cups from ice. Throw an insulated membrane in, and you could make a heated swimming pool. This is clearly the fastest and cheapest way to build a city but I'd put airlocks at various points to compartmentalize, just incase of a catastrophic break…. although that is only going to happen if you build too large or too close to the surface. With the low gravity, you could build some pretty large rooms…. maybe a football field or such, safely.
You didn't mention energy. While I think nuclear would be awesome, I think the best thing you can do in situ is wind turbines. Solar panels only last about 30 years or so and not at all during the night or the months long summer dust storms. A machine shop should be able to build the generators easy enough and the blades will need to be big but there is a steady 15 mph wind day and night, even better in dust storms.
That idear of cities on Mars under ground is what i call a obvious answer . For me I would live anywhere on Mars as long as I have all the necessary facilities to live with.
The problem with this idea is getting people to Mars without exposing our settlers to excessive radiation.
There is no technology we have that can see through the different layers of any planet or what the core is like… unless there is a device that can see all layers and knowing its composition including the core – though among ancient civilizations and indigenous people having knowledge or lore from passed down verbal record or tales suggests there is a hollow Earth.
No one has ever traveled or having a drill rig that burrowed straight to the core neither – it has been for a long-time fiction and theories – we do have tech that can somewhat penetrate surface and near surface land mass or using spectrum optics on satellites to an extent but not clearly to see and analyze the entire planet or moon or have done so to gas giants.
I like science fiction too. It would be 1000X easier to build a giant city here on Earth under the sea floor. Not saying that would be easy or even possible but that would be here on a planet we know has everything we need, wouldn't take any rockets or require human beings to adjust to another planet's gravity. Has it been done? How are the 'artificial islands' of Dubai doing? Enjoy the fiction but remember this is BS and there is no plan B for Earth. We live or die on the Mother.
I am an Earth Firster! So I say we mine the Earth first then Mars. "I might also be a Republican." 😎😎
Don't bring any identity politics to Mars please

we gotta solve a few problems first before even thinking of bringing people to Mars , such as Artificial Gravity and Radiation Protection and better speed of such a craft would help too , Seriously , otherwise we could be bringing Dead people to Mars , not so beneficial
I would rather go to Tahiti.
if there was thermal heat under the surface of Mars wouldn't it be likely that some heat would escape through these volcanic tunnels formed many years before ? , and could become water closer to the surface or even ice as it found far cooler temperatures near the surface
There is already an underground base on mars. It’s unacknowledged tho.
The lower the magnetospher protection, the more submerge surface one has to naturally render from radiation & life to grow. On the Moon, you cannot colonize easly on surface, but a space-RV craft camp burrowing is feasible, between surface safari play. It's safer to cycle a 28 days & night tourism than to pack colonize vs catylisms chance.
I'd take the chance to live in a domed city or beneath the surface on Mars. I'd even accept the fact that I'd die and be buried or cremated on Mars.
Why the holy F should I listen to a guy who gets his cues from Elon Musk? I have blocked your channel.
Just need heavy machinery, steel, concrete, food, water, oxygen, power and people stupid enough to believe this crap
All Homo-Sapiens are "Cave Monkeys" anyway.
At least in a domed city, you can see the sun rise and set. You won't feel enclosed in a tight place that might cave in on you one day. Humans are not moles or gophers. We need to see natural light. They should try building a colony that is subterranean and at the same time is above the surface.
Why would anyone willing to leave the comfort of a paradise such as earth to live on a hell hole like Mars ???
Mars is a failed earth don't you get it? "MARS IS DEAD!!!" Only robots can live there any human attempt of a Mars colonization will inevitably end up in complete annihilation so good luck…
No
Lol, we can not handle our planet and we want to colonize hostile Mars?…inside caves,…really?.
That’s a long add for a short clip. Unsubscribed
Yes to the domes in a cave while the solar power set-up are on a safe space on the rocky top surface to provide electricity in the caves
I'm not sure that, as life on Earth was about to be destroyed by a huge asteroid, I would be comforted by the thought that a few people on Mars would be able to survive. It would be fabulously expensive to set up a colony on Mars. The ISS cost over $100 billion to build. It can only accommodate a handful of people and cannot make its own food and air.
One proposal to build a city on Mars called Nuwa would require a volume of tunnels nearly 40x the Channel tunnel between England and France which was a huge engineering project. Even if sufficient lava tubes exist, fitting them out to live in will be very difficult and expensive.
It will be a challenge to make Martian technology completely independent of any input from Earth. For example if you wanted to build an electric car you would have to find sources of lithium, cobalt, nickel, copper, neodymium and some other things as well. You would have to mine the minerals and put them through an intricate web of specialized technologies before you had something that you could use. The large population on Earth makes it possible to have a large number of specialities, something which will be hard to replicate on Mars.
It's possible to imagine people going to live long term on Mars but its not easy to see how the settlement 100% self sufficient in the long run. It's not like going to live on island, relying on basic farming and building a house from stone and wood. Even in that scenario making tools without outside help could be an issue.
Don't worry,we would not build apsolutelly nothing,if thst was so easy we would build something on moon already but NASA are sombig Garbage that in 60 years they still need several years to send 3 guys in rocket on the moon just like in 60-s
The new Human race that will be decendents of us; well, we start again as a cave-people. We've done it before right? this time we have tech toys.
what do you think the governing system will be?
